Analysis of heating intensity and energy saving potential based on degree-hours method
The temperature and heating intensity requirements vary at different times of the day.Providing refined heating services based on the heating intensity requirements at different times can effectively save energy.Using linear propensity estimation method and degree—hours method,this paper analyzes the characteristics of temperature,initial and final heating days,heating length,and heating intensity changes during the heating period of Boli County,Heilongjiang Province from 2012 to 2021.As the temperature changes,the start date of heating in Boli County is postponed and the end date is advanced.Shortening the heating period and reducing the heating intensity can reduce heating energy consumption.The heating department can intelligently provide heating on an hourly basis during centralized heating.Based on the changes in hourly average temperature and the distribution characteristics of heating intensity,the hourly heating intensity can be flexibly adjusted,energy use can be reasonably planned,and resource waste can be reduced.
